to watch it now the 70 years dw, the we cons exactly say that we treat the plunge world with respect we are constantly exploring science at every opportunity and we try to optimize them through breeding engineers. think modification. the plants are extremely sensitive to external factors like noise, for example,

the hello and welcome to tomorrow. today, d, w, science magazine. most people don't give enough credit. that's a mistake because these extensively simple life phones have many amazing abilities of tool for them. it's also a question of easing oh, be need to around $800.00 chance these. these are kind of varies. they can catch flies and can even eat small pieces of meat. and they display in large variety of different strategies for catching pray. carnivorous plants everywhere you look 36 years ago, then file kind of founded the carnivorous plant nursery in the southwestern town, a fine time now the largest in germany. and no one knows better than he does how

the mysterious plants catch their prey. these carnivores all employed very different strategies. sorry, seni a for example, sets a pitfall trap. yeah. on the plan. so creates director here at the edge of the end here at the mouth, so to speak. next style associated with the anecdotal and the nectar attracts, the insects inside the land. lot start leaking are quite enthusiastic about it, like some more and more and more. then the plant i'm, it's a gas on which makes the insect a little bit dizzy, less the intake, and so piece you in the to continue to look the nectar and, but there are a little harrison, the 2 x which are directly downwards. that means it's easy to go down, but sliding back up is difficult, almost impossible for the flies line. so i hope they don't get the other. and at some point they just fall in and are guns. but it's amazing that the behind has

evolved so cleverly at 6 and bigger type this one on calculus. there are countless species of the star city of gina's in many different colors. these flowers even use its blossoms to catch prey. this particular strategy is that they bloom 1st, so the insects come to accommodate them, toys, and then when the blossom and weather after they forms 200 feet on the insects 2 or 3 weeks later, for additional no trails veda, only doubts. who is that position? now and so the common attendees, also known as tropical picture plants, use pitfall traps as well. sweet nectar on the smooth picture. rim attracts the insects which then fall into a liquid containing digestive enzymes where they drowned and are digested. some plants have even develop letters to lower ends, for example, into their deadly trap. other carnivores use,

so called glue traps. yes, indeed, see it, fine. so now we're here with the sun. new plant instead catches insects by attracting them to its due until the sun do refers to the adhesive droplets that glisten in the sun on. the insects then fly onto them out. they smell interesting. but once they're on it, they gets stuck to the adhesive droplets. these tend to goes and push the insect to the middle of the lee, understand how to apply. sometimes the leaf and crows around the insect, and enzymes start digesting the tract. pray on the funding to void it. so if at that one, butter word also catches small insects with a sticky, liquid unimed sleeves and the more prey it absorbs, the more it grows and blossoms. the best known carnivores, bc's is bertina, slide tribe. it closes its catching pedals around the pray originating from the us east coast. even charles darwin was fascinated with this plants. deadly snapped

traps. so shy that plan, so creates nectar and it's travis, that's it. and there are small contact chairs inside the bend. if even when the flies look the nectar, they automatically activate these contact chairs, not mac, suggest the plans the 1st time it happens, the plan registers agents in the 2nd time the plan senses that there must be something in there stealing gets nectar climb. so it snapshot as a kind of ask, identify, so very small prey like ads can still climb out to see your competition, you know, but a fat house by can some of the plans and the lose least as i said now, the plan performs and analysis is what i called protein retro now to event. now be the house on is this? if not it will open up overnight to the pray hours to spin into my hours for sheet . and if it is protein rich and then the plant begins to digest it in the stuff of household and in the put on some carnivorous plants are an amazing example of some

of nature's most sophisticated techniques. now onto the plants that humans eat according to a study by the world economic forum, the number of people living on a plant face died is decreasing, especially in highly population countries like india and china. on the other hand, in gemini and other western countries, the number of people giving up meat is on the rise. some people explained the shift by claiming that john face died so healthy it. but is that really true? a diet without any or dairy products. some would call it mountain nutrition, and others completely healthy. lots of people have an opinion, but if you have all the data on the nutritional scientist models, keller has been researching client base nutrition for 25 years. keller,

who is vegan, says that a vegan diet is in itself neither healthy nor unhealthy. the gun comes in because of thinking died can be very healthy if it's done right to die. you can also eat a very, very unhealthy vegan diet as cost a mix. diet is better than a bad reading diet, but very often it's the other way around. the beacons put more thought into their food, they are better informed and to make more wholesome food choices swell. how many studies over the years have shown that too much meat, especially processed meat is bad for your health. it's also being shown that a diet containing plan based foods is healthy or universe of the hospital in van. we meet the bobby. the nutritionist is a senior physician and professor of nutrition and metabolism at the university of bound. in her daily work at the hospital,

she notices time and time again. the positive effects of a vegan diet was adult while musa, very apparent in people's blood sugar levels. it's a little more just left with a much better profile is when people increase the amount of fiber they eat, their fish, the not it falls at all. that comes automatically when you eat a healthy vegan diet, like on the nod. and you can definitely see the positive effects on collector, all levels that come with the holes. and i had a $450.00 fee bid. click official plan. secondary compounds play an important role . they come from vegetables, fruits, legumes, or nuts, and give plan based fluids. their color, they have a positive effect on health, their anti inflammatory antioxidant, and can even reduce the risk of cancer. a plan based diet also provides other valuable substances. as safe, not ex faucet,

a or dietary fibers have a great a factory fees. they positively influence the micro biome dobs for the whole in general, the quality of carbohydrates is much better if you eat chick peas and lagoons or nuts with valuable fatty acids on slack, fully fed to, to all have. but what about eating up here? the vegan diet, the nutrition expert, is reserved in her response. there's always the risk of a nutritional deficit. and especially when it comes to vitamin b 12, it's needed for cell division and blood formation. and it's pretty much only found in animal products. in a strictly, fagan died, b 12 has to be supplemented in order to avoid the deficiency. in addition to b 12, there can also be deficits in calcium and omega 3 fatty acids, showing the trough make what color is always the question of how well we absorb a nutrient towards the natural. what is the bioavailability of these do trans hall?

actually you have to be pretty knowledgeable about that. what contains, what, how do you combine fluid? and how can you prepare the meal to make iron think it's lennier more available specific bodies. what about omitting gary products? the health benefits aren't clear, cut cheese, for example, often contains large quantities of fat. but to meeting them removes an important source of nutrients like calcium and iodine. studies provide evidence of reduced bone density in regions, but in the long term of the can die, i can have a positive influence on our health. for example, by reducing the risk of cardiovascular disease and type 2 diabetes. and there are indications that the risk of cancer might be reduced as well. for example, colon cancer, physicals and student need side of the the fight. i know the big studies definitely

indicates the same thing that it reduces the risk of diabetes. you know, i've seen it over and over again in cross sectional studies and in smaller cohort studies. i'm, so there's a strong indication of a causal relationship, doc, i invite style stuff so, so what does this cost? it can be done. this is on the switch medical expert says that eating a vegan diet requires a large amount of nutritional knowledge falls less hazel. that's integrated, a quote, integrating plant base foods in your die. it always makes good sense of the law visual duty. she usually lacks law, but the data doesn't show that it has to be a purely vision diet to read the benefit was like all see a moment, then we can nutrition as possible and can have a positive influence on your health. but it's not the only healthy way of eating the something that's perhaps even more controversial is the consumption of genetically modified

crops. nearly 20 years ago, the n t much tomorrow also became the world's 1st domestic, a modified organism to be marketed for consumption boss. it didn't appeal to consumers in the us and cost because they were afraid of eating genetically modified food. it has to be pulled from the markets, but efforts to genetically optimize tomatoes, continue these to monetize lip deceptively normal. but some of them have magical powers. they've been edited to produce victim indeed suntrust hope these plans will help to fight to very wide spread like a victim indeed. and humans. one of the world's major health problems for research team and u. k. genetically manipulated the tomatoes with tiny genetics is, is called crisp across 9. you can see here in a few trial week roll of the tomato, which is not just as motto,

and so our basement each month. so in parallel to the call really is how that differs within is that good thing is in tomato we didn't see any you loss or a gross defects for those. so i, this is most close and it just takes like tomatoes to make these tomatoes, the scientist fuse the domestic scissors and change them on the cubic tomatoes already have privates men, d, 3, a close relative victim. indeed. prove it. 20 is actually a building local victim. indeed. over to me in the 3 to be exact. that's what i've, what he needs. normally an enzyme, a blue collar worker in the tomato yourselves. would you use the private timidity to produce another molecule collateral? but the genetics is stop the enzyme in its tracks.

that means business as usual for prey, richmond. d 3 permits, men. d 3 can not be used to build victim. indeed. ready when private men d 3 is hit by the sun's rays, it's magically transformed into victim. indeed 3, that's the one we need to stay healthy. the modified victim, indeed tomato plants work just like the regular relatives. that's what the result just came. the seeds which carry the genetics seem to be photo and should go on to produce more plants with the fitment in the. ready each gene edited fruit has around 2 micrograms of victim, indeed inside it, between 2 and a half and 7 of these tomatoes daily could provide us with the amount recommended by w. h. of the good news is to mazda is a popular in 2021. 189000000 metric tons with produced globally mold and sugar, but not as williams,

but not everybody's open to genetic deals to the food. in fact, how for the public think it's on the safe. that's what the pew research center found when they asked people in 20 countries between the years 2019 and 2020 the way the richmond d tomatoes was produced with the genetic says as though it's close to nature, then you might think that's what the scientists claim those mutations are called naturally equivalent. that's means that it could happen in nature. the natural process. i think that's the beauty of searching. i just thing you don't bring any for james in the to month regina them. so they are the that is, has been fixed in the some authors, you know, there's no other things can happen in those tomato lines. need to moxie lines and now being tested in the field trials to see if they have any growth defects. and if they haven't equipment harvest,

they're also being tested on humans to see if they can absorb the victim. indeed, if need to actually succeed, they might play a role in fighting the lack of victim. indeed, worldwide, a basement deficiency is a big house problem globally. and approximately 1000000 people worldwide stuff us from basement, the insufficiency, no mention and developing countries or they're not developing countries. so the problem is we have very limited food source of basement to especially basement these re early a few foods have consequential amounts of it to me in the inside. for example, fish an eggs the skin can also produce an amount of victim indeed itself. but i need to get some of some lights and it's hard to get sufficient amounts to determine from the source of the name. the victim indeed is vital for many body functions

that helps the body of so calcium and phosphate essential for binding strength strung bones and necessary to support the weights of our in bodies and to move to run on surround without enough victim. indeed, funds become portal and break much more user name, deficiency and victim indeed has also been linked to a number of illnesses including depression. the. now the scientists type these tomatoes could help a number of people people were stuck, committed scaling, but how problem of, of self easily be lives which is essential to produces the source of basement d, y human. so that's why they're thinking africa also um is, has a relatively high bas, empty deficiency rates in the, in their population. and reset, chosen, looking at different ways to use the genetic editing techniques to possibly

engineered in tomatoes, also existing in august. so the next just crops such as pep talk to so ann over jane. so does fetch the pose of also a pulse both to be either said was accumulated to the amounts of for pro basement these rate. that's also a walkabout carry on a moment, tomato still need to pass clinical trials and off to it, there's no guarantee that there's some 1000000000 people that can victim indeed would eat them. but if the tomatoes succeed, the hope is fewer people would suffer from victim. indeed the efficiency is what is read. why do you have a science question? send it to us in a video text or voice message. if we onto it on the show, we'll send you a little surprised as a thank you on just task this

week, august, and comes from a how much below yellow from sierra leone. the, how does noise affect plants? the the world has been getting louder for decades. and it's not just humans and animals that suffer from the increasing noise levels. so do plans. they don't have years, but they can still receive sound. waves. plants produce messenger substances that they use to transmit sensory stimuli to their organs by a network of these things. in 6 use the same process, these beat their wings at the very specific frequencies to stimulate the release of common in certain plans. this evening,

primrose responds to buzzing sounds. within minutes of detecting these are months, the sugar content and it's nectar increases by up to 20 percent. the studies have shown that fail. chris can even distinguish between certain sounds and tones. whenever the plan sensitive predator gets a created toxins to protect itself. but the vibrations of the wind didn't trigger the defense mechanism. experiments have shown that sounds can even change the activity of genes after 5 days of continuous noise. the activity of several genes change in the sale, chris and the activity of photosynthesis decreased. the noise also

affects plants by animals because it scares away birds and pollinating insect researches in the us study the long term consequences over a period of 15 years. as they looked at the vegetation in quiet regions in places where a noise source had been removed and in areas that had been subjected to the constant noise of natural gas mining. before the study began, the comparison of the 3 areas showed that constant noise decreased the biodiversity of vegetation in the allowed areas a certain pine had diminished by 75 percent. juniper trees need jays to spread their seats for reproduction, but the jays didn't return to areas after the noise source had been removed. other species had grown in place of the junipers, which shows that noise can have long term effects on plants the

now so something completely different. when lions rule, they mocking the 2 or 3. but that doesn't always make it easy to determine the location. students at the design, university of technology have developed a digital acoustic device that can locate loud animals up to 500 meters away. and they tested on housing roles the this sound has given us chills since the dawn of time, the wolf. how is also an important sound for the game keepers who monitor them but keeping a close watch over them around the clock is impossible. a trip to the outs where the game cheaper is out with a young entrepreneur named olivia staley. staley wants to help gain keepers monitor

wolds more efficiently with the help of artificial intelligence and a special device, wildlife, a wild life and box can automatically locate, will not buy their housing food that housing the wolves can be heard for more than 3 kilometers away. so we can cover large areas completely cheaply and automatically when a, how it has been detected. it sends a message to the game keeper in real time, the sort to the device that's daily developed can locate a wolf's how to an accuracy of 500 meters. in my mind, from many animal monitoring methods require human made tools like photo traps space for the what was in particular can sometimes allude us exist. they remember where the photo traps are, because they don't like the flash or the sounds they make so. so they go around the photo traps on with our method before we want to trick the woods by engaging in

their methods of communication. and that way we can collect the data and sort of open on the same sol, off the some and then, and we can actually cover this whole area here on so could be optic at the switch, federal institute of technology and most on stanley developed a device with 3 other students, they set up 30 devices in the area for their research. noah schmidt is the company's technical manager. this is you should, this is what we call the smart mike. it's a device based on the raspberry pi, a mini computer you have to, they're still in the computer. it has gps and cellular reception, which is used to transmit the audio, or that i would just throw books on the bit. the sounds are sent to the servers and the audio files are converted into images. ringback artificial intelligence evaluates the images and identifies whether or not it's a wolf cell who,

if a wolf is located, a game keeper gets a notification immediately. according to a game keeper, michael bonds at the devices could be used to prevent wolf attacks in monitor pac formation. or the device could also assist with shootings through let them know the sooner that she would start the pack is a special protection status to that the device, it tells you where the pack is for you. and you can determine if a female is with the pack boone and seeing which direction they're moving along. so if you know with the pack is, you know, you have to be careful about shooting loan wolves around the earliest, one was but it was supposed to meet the meet them and oh, it's really helpful with a specific fee, low. the stupid things for staley says several swiss regions are interested in the product as, as the world wildlife fund it's use doesn't have to be limited to europe. may have to commit to submit this newton. i'm afraid of, of when we discovered that this works for more than just the was going on pay this

test. we were in south africa in the spring and tested it on elephants, lions, and hi eunice. and it working to me a bottom being told from last name to the, for the artificial intelligence could make handling wild animals much easier in the future. that was it for tomorrow. today dw science program will have more exciting stories next week. pennsylvania state, curious by the
